Slope Calculation Tool is an iPhone application developed by Riyad Habash. This free app falls under the Education & Reference category and provides users with a convenient way to calculate various measurements related to ramps. With just two inputs, the app accurately calculates the slope (incline), run (horizontal travel), ramp length, rise (height), slope percentage, slope ratio, and slope angle.

The app offers multiple scenarios for calculation. Users can input the run and rise, run and length, rise and length, or the slope percentage, ratio, or angle along with any of the other three measurements. By simply entering these values, the app quickly calculates the remaining information.

In addition to its calculation capabilities, the Slope Calculation Tool also features a built-in tool to measure the slope of an existing ramp or surface using the iPhone's capabilities. It is important to use a proper protection case to prevent scratches and ensure a flat shape for better accuracy.

With its accurate calculations and convenient measurement tool, Slope Calculation Tool is a valuable tool for anyone working with ramps or surfaces that require slope calculations.
